Paying taxes isn't any fun, we know, but still—you really shouldn't threaten to kill the IRS agent who's asking about the money you owe Uncle Sam.

Andrew A. Calcione, 49, of Cranston, Rhode Island, faces a possible lengthy prison sentence after making various serious threats against the IRS agent tasked with collecting more than $300,000 Calcione owed in back taxes and penalties. Calcione had apparently not paid taxes during the years 2008-2010.

During the course of attempting to collect the money, the Warwick-based IRS agent left a voicemail on Calcione's machine, which seems to have set him off. He called the agent back and, in two recorded messages, threatened to torture and kill the agent, rape the agent's wife, and harm the agent's daughter.

Calcione may receive up to 20 years in prison for failure to pay taxes and for the subsequent threats against the agent and his family. United States Attorney Peter F. Neronha made the announcement Monday, adding:

The vast majority of Americans understand the payment of their federal taxes is part of their civic responsibilities. A very small number do not, and an even smaller number not only refuse to pay their taxes, but engage in the kind of outrageous, threatening, and frankly bizarre behavior involved here.
